In the Poetical one, Aristotle elucidates the difference between history and the poetry. While history presents a description of the real facts, that is, what it really happened; the poetry demonstrates what it could happen, the point of view of the probability and the necessity. Being appraised as the quality of what it is likely or verossimilhante, it is similar to the truth having appearance of the true one, that is, approach of the real world. We can stand out in the Lisstrata workmanship the probability, for being tematizado in the text true events, descriptions and Reals. Although that, in way to the workmanship improbable events for the reality of the time to exist, as already it was cited previously. The dialogue between Lisstrata and Cleonice that the part opens is rich in concernentes aspects to the representation on the woman. The protagonist affirms that ' ' if it was for a bacanal or seemed thing, nor would have been necessary to invite them.

As she is for serious thing, so far no woman apareceu' ' (ARISTFANES, 2006, P. 13). Lisstrata speaks of the vision that the men had of the women as being malicious beings and Cleonice agrees to the illustration of malicious, but alert the friend for the fact of that the social situation lived by the women made it difficult the exit of them. In this dialogue between Lisstrata and Cleonice the function is clear that both exert. While second it fulfills the paper conformistical of the woman, the first search to show the action potentialities that they can exert. Through the dialogues the characters of the personages are observed, all they being well or badly succeeded as the ideas and the character that demonstrate in the actions. In the tragedy, catarse is the release of the tension that the spectator feels when attending definitive actions of the part.
